Americans who once shelled out extra for oat and almond lattes are increasingly heading back to the dairy aisle. Market research firm Circana says sales volumes of non-dairy milks have dropped more than 5% a year for three straight years, even as traditional milk still brings in close to $18 billion annually in the US. Shoppers cite high prices, thin protein counts, and long ingredient lists as turnoffs; one former alt-milk loyalist tells Bloomberg she switched back because cow's milk is "just one ingredient."
That shift is pressuring brands that soared during the 2010s plant-based boom, Bloomberg reports. Oatly's market value has shrunk from about $12 billion at its 2021 IPO to under $500 million, and giants like Nestlé and Unilever have pared back their plant-based lines. Companies are scrambling to respond with higher-protein blends, new flavors, and barista-focused products, even as oat milk remains popular in coffee shops. Almond milk, however, has seen the steepest decline, with a 9% year-on-year drop in 2025, Dairy Foods reports.
Analysts say consumers now favor simpler, recognizable foods, and dairy benefits from its built-in protein and "whole food" image—plus a price tag that often undercuts plant-based rivals. "The return to whole, unprocessed milk is about a desire for control," Eve Turow-Paul, executive director of food sustainability group Bite, tells Bloomberg. "When people feel like the world is chaotic, they gravitate towards foods that are simple and easy to understand. And there's simplicity and comfort in what seems Old World. It's like 'no one can trick me.'"
